27 Apr 2015 | | Abstract: | Thanks to the large collecting area (3 x ~1500 cm$^2$ at 1.5 keV) and wide
field of view (30’ across in full field mode) of the X-ray cameras on board the
European Space Agency X-ray observatory XMM-Newton, each individual pointing
can result in the detection of hundreds of X-ray sources, most of which are
newly discovered. Recently, many improvements in the XMM-Newton data reduction
algorithms have been made. These include enhanced source characterisation and
reduced spurious source detections, refined astrometric precision of sources,
greater net sensitivity for source detection and the extraction of spectra and
time series for fainter sources, with better signal-to-noise. Further, almost
50% more observations are in the public domain compared to 2XMMi-DR3, allowing
the XMM-Newton Survey Science Centre (XMM-SSC) to produce a much larger and
better quality X-ray source catalogue. The XMM-SSC has developed a pipeline to
reduce the XMM-Newton data automatically and using improved calibration a new
catalogue version has been made from XMM-Newton data made public by 2013 Dec.
31 (13 years of data). Manual screening ensures the highest data quality. This
catalogue is known as 3XMM. In the latest release, 3XMM-DR5, there are 565962
X-ray detections comprising 396910 unique X-ray sources. For the 133000
brightest sources, spectra and lightcurves are provided. For all detections,
the positions on the sky, a measure of the detection quality, and an evaluation
of variability is provided, along with the fluxes and count rates in 7 X-ray
energy bands, the total 0.2-12 keV band counts, and four hardness ratios. To
identify the detections, a cross correlation with 228 catalogues is also
provided for each X-ray detection. 3XMM-DR5 is the largest X-ray source
catalogue ever produced. Thanks to the large array of data products, it is an
excellent resource in which to find new and extreme objects. | | Source: | arXiv, 1504.7051 | | Services: | Forum | Review | PDF | Favorites | |
